ROLLER BEARING.

T0 all whom t may concern:

Be it known that I, FRANK P. MURRAY, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful improvements inRoller Bearings, of which the following is a specification.

My invention relates to roller bearings. The object is to provide abearing which is practically frictionless, which is adjustable to takeup the play caused by wear, which will take up the thrust and which is-simple and durable in construction.

This object, and other advantageous ends which will be describedhereinafter, I attain in the following manner, reference being hadto theaccompanying drawings in which- Figure 1 is a central section through abearing constructed in accordance with my invention,

Figure 2 a section on line 2-2 of Figure 1,

Figure 3 a section on line 3-3 of Figure 1,

Figure 4 an inside face view of an adjusting ring which forms a partofmy invention, and

Figure 5 a sectional perspective view of a thrust ring which forms apart of my invention. i

Referring to the drawings, 1 indicates a bearing casing made in sections2 and 3. A ring 4, provided with a pair of inclined races 5, is fittedwithin the casing and locked thereto against rotation by securing bolts6 passing through the casing and having their central parts passingwithin grooves 7 in ring 4. I A shaft 8, provided with a pair ofinclined races 9, is disposed within the casing so that its races 9 areopposite races 5. Two sets of rollers 10g, of frusto-conical shape, aredisposed between races 5 and 9 so that when the shaft rotates, it willroll on the frusto-conical rollers. The outer end 11 of each roller isprovided with a. ball race for receiving balls 12. A thrust ring 13 isprovided for each set of rollers and has ak flat inclined race 14 on oneside which engages the balls 12 and a ball race 15 on the other side forreceiving balls 16. An adjusting ring 17 is provided for each set ofrollers and has a threaded part 18 for taking into the threaded ends ofthe casing. The adjusting ring is provided with a ball race 19 forengagement with balls 16 and an integralV flange 2O notched in itsperiphery for receiving a spanner wrench or other suitable tool forturning the ring to adjust the conical rollers. The adjusting rings areheld in adjusted position by set screws 21 or other suitable means. i

When the bearing is in use and has worn to an extent where the play isobjectionable it is adjusted by loosening the set screws 21 and turningthe adjusting rings 17 so that the rollers will be forced inward untilthe play is taken up. The set screws are then tightened to hold therings in adjusted position and the bearing is again ready foruse. lThefrusto-conical shape of the rollers, in

connection 'with the thrust rings, takes up the thrust of the shaft. Theballs 12 on the ends of the rollers and the balls 16 between the thrustring and adjusting ring reduce the friction caused by the thrust to aminimum.

A bearing constructed as above described may be easily and cheaply made.All parts are simple and require simple machining.

While l have described my invention as taking a particular form, it willbe understood that the various parts may be changed without departingfrom the spirit thereof, and hence I do not limit myself to the preoiseconstruction set forth, but consider that t I am at liberty to make suchchanges and alterations as fairly come within the scope of the appendedclaims.

Having thus described my invention, what 1 claim as new and desire tosecure by Letters Patent is 1. A bearing including a casing providedwith inclined races; a shaft provided with inclined races; rollersbetween the races; a thrust ring disposed at the ends of the rollers; anadjusting ring mounted in the casing, and anti-friction means betweenthe thrust ring and the adjusting ring and the y ends of the rollers andthrust ring.

2. A bearing including a casing provided with inclined races; a shaftprovided with inclined races; rollers between the races; a thrust ringdisposed at the ends of the rollers; an adjusting ring mounted in the casing, and balls between the thrust ring and the adjusting ring and theends of the rollers and the thrust ring.

3. A bea-ring including a casing provided with inclined races; a shaftprovided with inclined races; rollers between the races; a

thrust ring hving an inclined race on one In testimony whereof I havesigned my side and a ball race on the other side, disname to thisspecification in the presence of posed at the ends of the rollers; anadjusting two subscribing Witnesses.
